A virtual-router routing instance, like a VRF routing instance, maintains separate routing and forwarding tables for each instance. However, many of the configuration steps required for VRF routing instances are not required for virtual-router routing instances. Specifically, you do not need to configure a route distinguisher, a routing table policy (the vrf-export, vrf-import, and route-distinguisher statements), or MPLS between the service provider routers.
Configure a virtual-router routing instance by including the following statements:
-
description text;
-
instance-type virtual-router;
-
interface interface-name;
- protocols { ... }
You can include these statements at the following hierarchy levels:
